Definitions

  • the present invention relates to flash devices and, particularly, to a flash device capable of emitting light with desired color and an image capturing device having the same.
  • Image capturing devices such as film cameras, digital cameras, and mobile phones equipped with a camera module, typically employ a flash device to illuminate an object in low lighting.
  • a typical flash device can only emit light with fixed colors, and users cannot vary the color, tone, and color saturation of the object to be photographed.
  • FIG. 1 is a functional block diagram of an image capturing device according to a first exemplary embodiment.
  • FIG. 2 is a partial, schematic view of a flash device of the image capturing device according to the first exemplary embodiment.
  • FIG. 3 is a schematic diagram showing the principle of detecting a color index position of a color filter of the flash device of FIG. 2 .
  • FIG. 4 is a schematic, isometric view of an image capturing device according to a second exemplary embodiment.
  • the image capturing device 100 includes a flash device 10 , a processor 20 , a color selecting module 30 , an image capturing module 40 , and a sensor 50 .
  • the flash device 10 includes a flash module 11 and a color wheel 12 .
  • the flash module 11 includes a flash lamp 111 and a trigger circuit 112 for triggering the flash lamp 111 .
  • the trigger circuit 112 is electrically connected to the processor 20 .
  • the color wheel 12 includes a motor 121 with a rotating portion 121 a , a color filter disk 122 attached to an end of the rotating portion 121 a , and a driving circuit 123 for controlling the motor 121 .
  • the driving circuit 123 is electrically connected to the processor 20 .
  • the color filter disk 122 is placed on the light emitting path of the flash lamp 111 .
  • the color filter disk 122 includes a plurality of sector-shaped filter segments. Each of the sector-shaped filter segments can be inserted into the light emitting path of the flash lamp 111 by rotating the color filter disk 122 .
  • the color filter disk 122 has a red filter segment, a green filter segment, a blue filter segment, and a white filter segment.
  • the color filter disk 122 is configured for changing the color of the emitting light from the flash lamp 111 , and as a result, the color, tone, and color saturation of an object to be photographed can be changed.
  • the rotating portion 121 a of the motor 121 is configured for rotating the color filter disk 122 .
  • a timing mark 121 b is arranged on a circumferential side surface of the rotating portion 121 a .
  • the timing mark 121 a is configured to aid the sensor 50 to detect a color index position of the color filter disk 122 mounted on a end surface of the rotating portion 121 a during rotation.
  • the sensor 50 includes a light emitting diode 51 for emitting light towards the rotating portion 121 a and an optoelectronic diode 52 for detecting light reflecting from the rotating portion 121 a .
  • the timing mark 121 can be made of a black or dark light-absorbent medium with low reflectivity.
  • the color selecting module 30 is connected to the processor 20 , respectively.
  • the color selecting module 30 is configured to allow users to select a desired color of light emission from the flash device.
  • the processor 20 is configured for controlling the rotation of the color filter disk 122 by using the motor 121 and the sensor 50 according to the selection of the color selecting module 30 .
  • the processor 20 is further configured for controlling the flash module 11 while the image capturing module 40 is capturing an image.
  • users can select the desired color of the object by using the color selecting module 30 of the image capturing device 100 first. Then, the processor 20 will rotate the color filter disk 122 by using the motor 121 and the sensor 50 according the selection of the color selecting module 30 . Finally, the image capturing module 40 will capture the image of the object while the flash module is emitting light towards the object, and as a result, can get the image of an object with the desired color.
  • the image capturing device 200 includes a front surface 210 facing an object to be photographed, and a side surface 220 adjacent to the front surface 210 .
  • the front surface 210 defines an opening 240 corresponding to a flash lamp 230 of the image capturing device 200 .
  • a color filter disk 122 is placed on the light emitting path of the flash lamp 230 .
  • the difference between the image capturing device 200 and the image capturing device 100 of the first embodiment is that, in the present embodiment, the color filter disk 122 can also be rotated manually.
  • the side surface 220 defines an operating opening 260 for rotating the color filter disk 122 manually thereof.
  • the color filter disk 122 has a toothed circumferential side surface and can partially extend out from the operating opening 260 for ease of operation.
